Reduced‐section specimens conforming to the requirements given in Figure QW-462.1(b) may be used for tension tests on all thicknesses of pipe having an outside diameter greater than 3 in. (75 mm).
(a) For thicknesses up to and including 1 in. (25 mm), a full thickness specimen shall be used for each required tension test.
(b) For pipe thicknesses greater than 1 in. (25 mm), full thickness specimens or multiple specimens may be used,provided (c) and (d) are complied with.
(c) When multiple specimens are used, in lieu of full thickness specimens, each set shall represent a single tension test of the full pipe thickness. Collectively, all of the specimens required to represent the full thickness of the weld at one location shall comprise a set.
(d) When multiple specimens are necessary, the entire thickness shall be mechanically cut into a minimum number of approximately equal strips of a size that can be tested in the available equipment. Each specimen of the set shall be tested and meettherequirements of QW-153.For pipe having an outside diameter of 3 in. (75 mm) or
less, reduced‐section specimens conforming to the requirements given in
